The noticeable increase of scabies: New resistant Form?

Why spreads the scabies in Germany?

If the skin burns, itches, and is covered with pin-sized blisters, reddened nodules, or pustules, may be pushing the scabies mites to mischief. The tiny arachnids nesting, especially between the fingers and toes, on the wrists, ankles, under the arms, at the elbow, on the nipples and on the genitals. A skin expert reports on the striking increase of scabies in the last few years in Germany.

Professor Dr. Cord sunder Koetter is the Director of the clinic for dermatology and venereology at the University hospital in Halle. To 50. Meeting of the German Dermatological society (DDG), which took place recently in Berlin, informed the expert about the possible reasons for the increase in the scabies (scabies). Experts suspect that a medicinal product is resistant to mold behind the increased cases of the disease.

Puzzling increase in scabies cases

As the experts in the DDG report, has been made in recent years, strikingly often, the diagnosis of scabies. Since it is not scabies but to a reportable disease, there is no reliable data about how much the increase actually is. According to the experts, the scabies mite finds this to be particularly good conditions, where poor Hygiene prevails and many people live together in a confined space. Such conditions can be found in Germany, but only rarely. What explains the spread of the parasites?

Risk group: people with changing sex partners

“A group of experts has worked out the possible causes, is proved, as yet, not one of them,” explains the DDG. A risk factor for the Transmission is, for example, more frequent sexual intercourse with multiple partners (promiscuity). As the skin experts and skin experts, the DDG noted a rise in the number of sexual diseases, this could also have an impact on the spread of scabies.

Children under-appreciated source of infection

“Besides, children are an under-appreciated source of infection,” emphasize the DDG-professionals. In children, the disease will be diagnosed tend to be more frequent than in adolescents and adults. In addition, they often have more mites and not to be so treated rarely inadequate. In addition, children are looking for contact-intensive body, whereby the scabies mites more easily continue to spread. “In order to verify such a causal relationship elaborate epidemiological studies are needed”, explains Professor Dr. sinner kötter in a press release from the DDG.

Experts suggest a resistance to medicines

The Skin experts could not, however, observe an increase in disease cases, it is also more and more cases where the medicinal product for the treatment of scabies, the so-called anti-skabiosa, failed. The increasing resistance of the mite against the Antiskabiosum was also observed in other regions of the world. The Robert Koch Institute (RKI) reported in a FAQ for the scabies of two Australian patients with scabies who were treated several dozen times unsuccessfully with the drug. Usually only one or a maximum of two applications is required to eliminate the mites.

Every tenth treatment for scabies is unsuccessful

Professor Dr. sinner kötter sees three possible explanations for the lack of therapy. A faulty application of the drug may be, on the other, could have Affected after the treatment, re-infected, because there is no therapy in close contacts of people took place. Also a growing resistance to anti-skabiosa be a possible cause. For this purpose, there is yet no evidence. According to the data of RKI, one of ten treatments for scabies fail on average. (vb)
